In research for the Flemish-language magazine Knack, journalist Jean-Paul Mulders traced Hitler's living relatives in the Fuhrer's native Austria, as well as the United States.

Geneticists identify groups of chromosomes called haplogroups, 'genetic fingerprints' that define populations.

According to Mulders, Hitler's dominant haplogroup, E1b1b, is relatively rare in Western Europe - but strongest in some 25 percent of Greeks and Sicilians, who apparently acquired the genes from Africa.

Between 50 percent and 80 percent of North Africans share Hitler's dominant group, which is especially prevalent among in the Berber tribes of Morocco, Algeria and Tunisia, and Somalis.

More surprising still, perhaps, is that Hitler's second most dominant haplogroup is the most common in Ashkenazi Jews.
